Abstract
An hydraulic analysis was undertaken to obtain the source strength of dredge-induced suspended sediment using field data measured at Gunsan and Busan New Port sites. Applying Kuo and Hayes's(1991) analytical method,the suspended-sediment concentration and ambient flow velocity measured along plume axis were used to obtain the hydraulic parameters of turbidity plume dispersion.The andalytical solution was compared with the various field measurements including data sets of US Army Corps of Engineers. The results were generally in good agreement with the suspended-sediment concentration distributions at the dredging sites. The source strength og suspended sediment for each site was calculated using plume parameters. The result shows that the source strength increased in proportion with the ambient flow velocity,but was less dependent on the particle-size composition of dredged sediment.
